SPECIFICATION forming part of Letters Patent No. 465,344, ldated December 15, 1891.

Application filed June 19, 189i). Serial No. 355,950. (No model.) v

To all whom it may concern:

Be it known that I, JOSEPH CLARK, a citizen of the United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Lubricators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates, generally, to lubricators, and particularly to that class thereof in which provision is made for oiling wrist or cross-head pins and their bearings between the connecting-rods of steam-engines and their cross-heads, in which the sight-feed is embodied and in which are employed in connection with the delivery-pipes communieating with said wrist-pins and their bearings, knives, or Scrapers, which, duringuthe reciprocations of said connecting-rods and cross-heads, disengage small amounts or drops of the lubricant from said delivery-pipes and permit the same to descend by gravityto the parts requiring lubrication; and it consists in the peculiarities of construction and arrangement or combination of parts hereinafter fully disclosed in the description, drawings, and claims.

The objects of my invention are, first, to provide a novel and improved construction and arrangement of `parts for feeding the lubricant from lthe feed or oil-supply cup to the deliverycup,wherehy the downward passage of the drops of said lubricant will be clearly exposed to view at all times; second, to provide improved devices for the application and adjustment of my improved oiler or lubricator to engines of varying sizes and diferent forms or constructions; third, to provide novel means for feeding or delivering the lubricant to the wrist-pins and bearings of cross heads; and, fourth, to protect the lubricant in its passage to its final destination from being mixed with dust, cinders, and other foreign and injurious matters and to prevent saidlubricant from being sprinkled over the adjacent parts of the engine. These objects are accomplished by the improved lubricator illustrated in the accompanying drawings, forming part of this specification, in which the same reference-numerals indicate the Same parts, and in which--v Figure 1 represents a broken side elevation of the cross-head guide-frame of a steamengine provided with my improved lubricator, which is partly in section; Fig. 2, a detached View of myimproved lubricator, which is also partly in section and arranged'to comm-unicate with the wrist-pin and bearings of a cross-head, this View being taken at' right angles to that shown in Fig. l; Fig. 3, a partly sectional side elevation of the upper stationary vertically and horizontally arranged discharge-pipe, and also of the movable combined hollow sphere and the lower verticallyarranged discharge-pipe, these parts being disconnected or in the position they appear when the twoplatter are moved forwardly-or toward the former bythe kvcross-head of the engine; and Fig. 4, a Sectional plan view on the line x :n of Fig. 2.

In the drawings, the numeral l indicates the cross-head guide-frame of a steam-engine.; 2, the cross-head; 3, the wrist-pin thereof; 4, the piston-rod; and 5 the connecting-rod, all of any usual or suitable construction.

The feed or oil-supply cup 6, which may be of the form shown or any other suitable' construction, is provided atits top with the dared orfunnel-shaped filling-cup 7 with an interior needle-valve and stem, or any other suitable device for regulating or adjusting the dis.

charge of the oil therefrom,and at its bottom with the interiorly screw-threaded collar 8, within. which is screwed the upper end of the vertical feed-pipe 9, which is surrounded by downwardly-curved and relatively small discharge-pipe 13 is tapped or passed through the vertical sleeve lO and communicates with the vertical feed-pipe 9, which, at a point just below the inner end of said small discharge IOC pipe, is provided with the plug 14, which arrests the downward passage of the lubricant and causes it to flow out through said small discharge-pipe- The lower end of the vertical feed-pipe 9 is provided with the horizontal sleeve 15, within which is adj ustably secured the tubular supportI 16, which is held in place by the set-screw 17. rlhe outer end of the tubular support 16 is provided with a hollow ball 18, through which passes the upper vertical discharge-pipe 19, which is provided at its upper end with the flared or funnel-shaped oil-discharge cup 20, which is arranged directly beneath the outer end of the curved pipe 13, and receives the oil as it drops therefrom, after it passes through the intervening` open -air space, and which jointly produce a sight-feed which is far superior to those inc'losed within glass tubes or cylinders, as the latter become dirty and smutty and consume time and `labor in keeping them clean. This oil-discharge cup 2O is provided with suitable straining or filtering material 2l, for protecting the oil in its downward passage at this point from being mixed with dirt, cinders, and the like. Thelower portion of the upper discharge-pipe1 9 is tapered, curved, and extended horizontally forward, as shown in Figs. 1 and 3, so as to be in proper position for entering'and leaving the hollow sphere 22,

which is formed with the slot 23 in its side.

This hollow sphere is screwed or otherwise removably secured to the upper end of thelower discharge-pipe 24, and within the same and to the upper end of said pipe is secured the knife or scraper 25, which has its upperend arranged on a line passing 'close beneath the outlet of the upper discharge-pipe 19, so that during the reciprocations of thecr'oss-head 2 small amounts or drops of the'lubricant will be disengaged from the outlet end of said pipe and permitted to descend to the parts needinglubrication. This hollow sphere also excludes dust and other foreign matters from the ends of the adjacent discharge-pipes, and thus prevents the passage of the oil from being clogged or retarded. The slot 23 in this hollow sphere permits a strong air-current to enter therethrough and become concentrated or compressed within said sphere, and thus forces the drops of oilI from the knife or scraper downward and into the lower discharge-pipe 24' during the forward movements of the cross-head.

The advantages and operation of my im-v thence into the vertical feed-pipe 9 and the curved discharge-pipe 13 thence it drops into the discharge-cup 20, in which it passes through the filtering material 21, and thence through the upper and lower discharge-pipes 19 and 24:. The {iowof oil is regulated, as hereinbefore described, so that only a drop adheres to the outlet of the upper discharge-pipe 19. Hence when the cross-head travels forward and is at about the end of its stroke the knife or scraper 25 comes into contact with the out! let end of said pipe and scrapes off this drop of oil, which then remains upon said scraper until the cross-head again moves forward, when it is forced down into the lower dischargepipe 24 by the force of the compressed air entering the slot 23 in the hollow sphere 22, and then it courses downwardly until it reaches the Wrist-pin and its bearings or other surfaces to be lubricated. Among the other advantages of my improved lubricator are the open-air sight-feed, by which the feeding or dropping of the oil on its way to the parts to be lubricated may be observed wit-hout being obstructed by the glass tubes or cylindersv cant downward from the knife -or scraper; the

above-described facilities for the adjustment or adaptation of my lubricator to engines of different forms .and sizes and the great 'saving in oil which is effected by feeding the same in drops or minimum quantities to the surfaces to be lubricated. Y

Having thus fully described the construction and arrangement or combination 'of the several parts of my invention, its operation, and advantages, what I claim as new is-V e 1.
